SWELLING BEHAVIOUR OF UNDISTURBED AND REMOULDED SAMPLES OF BLACK COTTON CLAY

Swelling pressure of undisturbed and remoulded samples of black cotton clay from two locations in Warangal were determined by the free swell and the constant volume methods. In the free swell method, the maximum percentage swell was also recorded. The results indicate that the undisturbed swelling behaviour is different from the remoulded behaviour. Swelling characteristics test conducted on undisturbed samples collected in the vertical and horizontal direction indicated that their swelling behaviour is different, which implies that the insitu swelling behaviour may be anisotropic. Unlike free swell, the swelling pressure is unaffected by the changes in the initial water content and the surcharge pressure. Swelling pressure appears sensitive to the technique of testing. Swelling pressure values obtained by the free swell method have been found to be larger than those obtained by the constant volume method. (Author/TRRL)
